This innovative and richly illustrated set is designed expressly to stimulate young minds through an integrated approach to science. Designs in Science explains concepts in the physical sciences by linking them to principles in the biological sciences, thus highlighting the similarities between designs in modern technology and designs in the natural world. Each volume is an active learning tool that contains: -- Clearly defined key terms -- Full-color photographs and drawings throughout each section that enhance the comparisons between nature and technology and illustrate the principles discussed in the text -- Amazing facts and stimulating questions that encourage young people to move outside of the text and explore these principles at work in the world around them -- Easy-to-execute experiments that offer a hands-on way for students to verify the principles discussed. Readers will discover the principles and problems of movement in water, in the air, and on the ground. Comparisons are drawn between animals and machines, and topics are diverse.
